The version 3.1 hardware incorporates expanded memory to support automatic firmware updates of compatible connected accessory controllers.

Key Features:

• Dual-stage operation: Coordinates heating and cooling stages in supported equipment configurations.
• Digital display: Provides local access to operating status, configuration settings, and diagnostic information.
• Equipment interfaces: Connects controller logic to compatible thermostat signals, sensors, and controlled outputs.
• Low-voltage supply: Uses nominal 24 VAC power within the Smart Equipment control architecture.
• Expanded memory: Incorporates the 8 MB memory hardware associated with version 3.1 controllers.
• Accessory updates: Supports automatic firmware synchronization with compatible accessory boards when supported firmware is installed.
• Replacement reference: Replaces SE-SPU1002-1, subject to equipment configuration and firmware requirements.
• Optional communications: Uses a separate field communications expansion board for supported network integration.

The SE-SPU1002-3 delivers the reliability and precision required for staged equipment operation and local diagnostics in compatible commercial climate control systems.
